Question:
If your 2008 Toyota Tundra has the factory 7-way connector in the back, then you should be able to plug in a brake controller adapter under the dash of the Tundra. Does the connector provided by the manufacturer look like the Universal Brake Control Wiring Adapter, part # 3040-S. If so, then you will just need to connect the wires coming out of the back of the Draw-Tite Activator, part # 5504, to the proper wires on your factory supplied harness, and plug in the adapter. The brake controller wire functions are: White: Ground wire. Black: 12v lead wire. Blue: Electric brake signal wire. Red: Stoplight switch, this wire would have a power reading when the brake pedal is pressed, but would have none when it is released. You can view some additional information on installing a brake controller at the links provided.
